  2. 1. Uncertainty measurements and validation of ocean colour data in optically complex waters

    Author : José M. Beltrán-Abaunza; Susanne Kratzer; Samantha Lavender; Paul Glantz; Sven Blomqvist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ocean colour validation; MERIS; in situ radiometry; water quality; CDOM; marin- och brackvattensekologi; Marine and Brackish Water Ecology;

    Abstract : The thesis addresses validation activities associated with the use of in situ and satellite-based radiometers to assess water quality parameters, such as chlorophyll-a (Chl-a), total suspended matter (TSM) and coloured dissolved organic matter (CDOM- also known as yellow substances, YEL) in CDOM-dominated waters. In paper I, an inter-comparison of in situ radiometers is presented. READ MORE

  4. 2. Benthic metabolism and sediment nitrogen cycling in Baltic sea coastal areas : the role of eutrophication, hypoxia and bioturbation

    Author : Stefano Bonaglia; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Eutrophication; Sediment; Benthic Flux; Nitrogen Cycle; Denitrification; Baltic Sea; Biogeochemistry; biogeokemi; marin- och brackvattensekologi; Marine and Brackish Water Ecology; Marine Ecology; marin ekologi; geokemi; Geochemistry;

    Abstract : Eutrophication is one of the greatest threats for the Baltic Sea, and one of its more critical consequences is bottom water hypoxia. Nutrient enrichment and oxygen-depletion affect both the deep central basins and a number of coastal areas, even though strategies for nutrient reduction have lately been implemented. READ MORE

  5. 3. Round goby Neogobius melanostomus in the Baltic Sea – Invasion Biology in practice

    Author : Gustaf Almqvist; Magnus Appelberg; Sture (biträdande) Hansson; Johanna Mattila; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Round goby; Neogobius melanostomus; Apollonia melanostoma; non-indigenous fish; life history characteristics; predation; competition; Gulf of Gdańsk; Baltic Sea.; Marine ecology; Marin ekologi; marin- och brackvattensekologi; Marine and Brackish Water Ecology;

    Abstract : Human mediated transfer of non-indigenous species is considered to be a major threat to global biodiversity. The Ponto-Caspian round goby (Neogobius melanostomus), which has established populations in various regions in Eurasia and North-America, was first observed in Gulf of Gdańsk, Baltic Sea, in 1990.
